| 摘 要： | 昌特敖包花岗闪长岩体位于内蒙古中部苏尼特左旗南部,该岩体高精度的单颗粒锆石U-Pb年龄为362±4Ma(MSWD=0.005),这说明该地区确实存在晚古生代中期花岗岩,据此年龄和前人资料可将苏尼特左旗南部形成于晚古生代中期的花岗岩类划分为南北两个花岗岩带.

| Abstract: | The Changte aobao granodiorite is located in the south of Sonid Zuoqi,Central Inner Mongolia.The high precision single grained zircon U Pb age is dated as 362±4 Ma (MSWD=0.005),confirming that the pluton was formed in the middle of Late Paleozoic era.Based on this and other isotopic data,the granotoids formed in the middle of Late Paleozoic can be divided into two belts from north to south. |
